What the neuroscientist is discovering is both humbling and frightening him.

We understand conscious experiences only in light of our nature as living creatures.

For many of us over the last year and more, our waking experience has, you might say, lost a bit of its variety. We spend more time with the same people, in our homes, and go to fewer places. Our stimuli these days, in other words, aren’t very stimulating. Too much day-to-day routine, too much […]

A neurologist makes an emotional visit to understand “resignation syndrome.”

How does consciousness arise? What might its relationship to matter be? And why are some things conscious while others apparently aren’t? These sorts of questions, taken together, make up what’s called the “hard problem” of consciousness, coined some years ago by the philosopher David Chalmers. There is no widely accepted solution to this. But, fortunately, […]

Our sense of time may be the scaffolding for all of our experience and behavior, but it is an unsteady and subjective one, expanding and contracting like an accordion. Emotions, music, events in our surroundings and shifts in our attention all have the power to speed time up for us or slow it down. When […]

Most neuroscientists accept that the brain computes by modifying its synapses, the links between neurons. On this view, the brain learns because experience molds it, rather than because experience implants facts. But experience does implant facts.
